put n parameter on the declarative part...this is the number of bins...
then multipli the s value in each horn section by n, the same for duct surface, compression chamber and rear chamber.
should be nice to use the rectangular form defining hth wth hmo wmo, so you can choice how do you stack the bins...vertical multiply h by n horizontal, w by n.

>>>Hope you are keeping up........
All nodes in a script link together for example, you would define a driver nodes 0 and 1, the rear chamber node 2, and then a series of waveguides, or acoustic horns nodes 3 and 4. The difference between a waveguide and a horn is that a horn is an output of sound, and a waveguide will be connected to another acoustic element in your design.
Hope you get the idea. By using the node method you have an unlimited amout of modeling can be done covering all acoustic systems.
Bee, I believe I can jump start my learning curve on Akabak by nailing down some of the lingo first. I’m currently reading three speaker books and loads of info on the net that I have located over the past couple of days to speed up the learning curve as well.
My first question in regards to Akabak is…. What is a waveguide?
Found this after searching in Google but still not quite grasping what a waveguide is and how we use waveguides in Akabak..
A waveguide is a structure which guides waves, such as electromagnetic waves or sound waves.
I just realized that my Akabak newbie question in the previous post appears on this "Advanced Discussion" Forum. Please let me know if this level of questioning is acceptable on this thread or if I should start a new thread in regards to "Akabak Newbie" on the "General Forum".
I just wanted to keep things together as my questions relate to what Bee wrote in this very helpful "Akabak for Beginners" tutorial thread. Thank you.
>>>wave guide is a part of the horn, lets say your horn has 3 sections each section is a differant size to the last, each wave guide makes up the overall horn.
Is the term "waveguide" associated with Akabak only? or is it an industry term in regards to speaker/enclosure design?
Also, when you say, "lets say your horn has 3 sections each section is a differant size to the last, each wave guide makes up the overall horn". Do you define waveguides as in my drawing below? My drawing is only 2 dimensional. Is 3 dimensional required? Thank you.
wally, depends how do you model the horn. You can mantain the height equal for all the elements like like in jbl2397 horn, or you can gradually enlarge it. If the width x height is the same for both options the spl shoud be the same (without floor) but the dispersion should be different.
However if you get the basic from the bee's how to, manual and help are pretty clear.
